What I'm unsure about is the position of the pickups & routes. As the jazz pickups are wider than the jag, the new route for the jazz bridge pickup would have to extend RIGHT up to the bridge itself, in order to position the pickup such that its pole pieces were where the pole pieces for the jag pickup were. A similar issue with the neck pickup - extending the route right up to the neck cavity (seems like a bad idea!).
So any suggestions as to where to place the pickups that is practically possible, and for the best sound?
